• the interlock 55 which may be of any conventional construction — senses when the door containing the housing portions 35 is less than fully closed, and if not fully closed will not allow operation of the cutter motor 46, so that if an operator has gained access to the interior of the housing 36 containing the cutter 29, rolls 20, 21 , etc , the safety hazard of the movable cutter blade 31 will not confront the operator
• Various other components may also be provided for the dispenser
• a manual advance knob 57 may be provided connected to the drive roller 20 for initially rotating the roller 20 to properly position the first label 15 from the roll 10 at the start of a new roll 10
• a roll 10 of linerless labels 15 is placed on the substantially vertical shaft 18 and the lead label from the roll is moved into the inlet 59 (see FIGURES 2 and 4) of the housing 36 so that the adhesive face 12 thereof is in contact with the roll 20 and stripping guiding fingers 22 plasma coated surfaces, while the release coat face 11 thereof is in contact with the roll 21 and the fingers 23.
• the manual knob 57 is rotated to drive the roller 20 until the leading edge 60 (see FIGURE 2) of the leading label 15 of the roll 10 is approximately at a point in alignment with the anvil blade 30 Then with the door portions 35 of the housing 36 closed, the operator presses the feed button 54 This initiates operation of the electric motor 45 which drives one or both of the rollers 20 21 in the direction of the arrows 61 , 62 illustrated in FIGURE 2, so that the label 15 cams the leading edges 42 of the spring fingers 41 out of the way and the leading edge of the leading label 15 passes through the exit slot 38
• the motor 46 pivots the movable cutting blade 31 from the position schematically illustrated in FIGURES 2 and 3 to the position illustrated in FIGURE 6, moving in the path 34 into operative association with the anvil blade 30 so that a scissors cutting action of the leading label 15 from the next label of the roll 10 takes place
• the movement of the cutter blade 31 is sensed by the optical sensor 53, which through the computer control 49 then terminates operation of the motor 46 after one revolution of the motor 46 in which the movable blade 31 is returned to its initial position as seen in FIGURES 2 and 3.
• the leading label 15, which has then been cut from the roll 10, does not fall out of the dispenser 19 since it is held in place by the spring fingers 41 biasing the adhesive face 12 thereof into contact the plasma coating 40. Operation of the motor 45 is blocked until the take away sensor 52 senses removal of the cut label 15. Once the operator grasps the cut label 15 and pulls it out of the slot 38, the take away sensor 52 senses this, and through the computer control 49 allows the motor 45 to be operated again when the operator pushes the feed button 54. Alternatively, the feed button 54 may be bypassed or done away with, and as soon as the sensor 52 senses removal of the cut label 15 (or after a short delay), the motor 45 may be automatically actuated by the computer control 49 to advance the next label 15 from the roll 10.
